Dumper truck and its carriage underbed

Abstract

The present invention provides one kind of dumper truck and its carriage underbed. The carriage underbed includes two longitudinal beams in the lengthwise direction of the truck body, several crossbeams and several wing supports. The longitudinal beams are made of channel section with openings in the upper part for the crossbeams to be embedded in vertically, and have relatively small height resulting in lowered bearing plane and raised running stability of the truck. The dumper truck has less parts and simplified manufacture process.

Description

technical field [0001] The invention relates to a compartment underframe of a dump truck and a dump truck with the compartment underframe. Background technique [0002] At present, a dump truck usually includes a head, a lifting mechanism, a compartment, a frame, etc. Among them, the underframe of the dump truck usually adopts a three-piece structure of longitudinal beams, beams and wing braces, mainly including the following components: channel longitudinal beams, beams, wing braces, longitudinal braces, reinforcement angles and other components. [0003] See Figures 1, 2 and 3. Fig. 1 is the front view of the carriage underframe of the forward-leaning dump truck in the prior art; Fig. 2 is a top view of the carriage chassis of the forward-leaning dump truck in the prior art; Fig. 3 is the carriage of the forward-leaning dump truck in the prior art Left view of the chassis. Other components of the dump truck are omitted from the figure. [0004] In the compartment under...

AI Technical Summary

Problems solved by technology

In order to facilitate the laying of the floor, the upper planes of the beams, wing braces and sides must be even, so the joints of the beams, wing braces and longitudinal beams have to be opened, which increases the difficulty of the process

In addition, in order to improve the load-bearing capacity of the longitudinal beams, the longitudinal beams must be welded into closed rectangular tubes; the longitudinal beams, cross beams, wing braces, longitudinal braces, reinforcement angles, fixing plates and pad irons and other components must also be welded with Welding connection, the process is very complicated, and the welding workload is also very large; and because the welding is easy to deform, and the correction process of the chassis needs to be added, so the splicing and welding process of the car phase chassis is quite complicated
